Limit Tests 10-13
A) FEED <name>
Name parameters:
• CALCulate1 — Limit tests will be performed on the result of a math calculation (mX+b
or percent).
• SENSe — Limit tests will be performed on the input signal. Note however, that Rel can
be used on the result of a math calculation as well as the input signal. Limit tests will be
performed on the result of the Rel operation (see CALCulate2:NULL). Details on rela-
tive, mX+b and percent are provided in Section 7.
B) <NDN> and <NRf> parameters
<NDN> = #Bxxxx Binary format (each x = 1 or 0)
= #Hx Hexadecimal format (x = 0 to F)
= #Qxx Octal format (x = 0 to 17)
<NRf> = 0 to 15 Decimal format
An output pattern is set by sending a parameter value that corresponds to the 4-bit BCD pat-
tern of the output. The parameter value can be sent in the binary, decimal, hexadecimal, or octal
format. For example, if you wish to set lines 4, 2, and 1 HI, the binary parameter value would
